Improve Overall Controls
❒ Environmentally Preferable Purchasing (EPP)
Raw materials review & purchasing program (SW)
❒ Inventory control: First In, First Out❒ Practice Waste Separation❒ Employee Training ❒ Inspect waste storage containers for leaks
-
Pre-Press Processes❒ Photo-processing
DevelopingCover developer and fixative containersMinimize dragout – rollers, squeegeesRecycle spent developer and fixer
Water rinsesOptimize bath temperature to 80 FWater conservation by intermittent water control Silver recovery from waste water
Reduce Solid Waste – improperly exposed film, packaging, containers, customer rework
Segregate and recycle
❒ Latest Trend --Increased digital work now –

Pre-Press Processes
❒ Press PreparationInspect rolls, machinery for defectsTest Proof
Reduce solid waste by proofing before running production.
Optimize press production planningMinimize solvent use for changes and clean-up.
-
Printing Processes
❒ Press Make-ready❒ Printing
Solid WasteSet up press carefully w/ test runs
InksSelection of inks w/ low metals, VOC content.Keep containers closedAnti-skin additive
-
Press Clean-up
❒ SolventSwitch to an automatic wash-up if possible (Reduce solvent by 1/3)Switch to least toxic solvent as possible (may require new ink)Minimize use by applying on towel and not machine. Recover solvent by distillation, microwave treatment, etc.
❒ TowelsLaunder and reuse after recovery process.
❒ Excess InkReadjust runs to reduce amount of excess ink. Filter and save for next color runSend to ink recycler for off-site treatment
-
Post-Press Processes
❒ Post-PressAdhesives
Select low VOC glues
Solid wastePlan layout before printing to minimize wasteMinimize overrunsRecycle trimmingsRecycle rejects
-
Resource Conservation❒ Latest technologies:
May require less energy, water, labor & chemicalsMay reduce set-up & make-ready times
❒ Monitor electric & water to determine:What activities consume them? Assign costs to those areas and activities.What measures might reduce usage?
❒ Monitor solid and hazardous wasteAssign & track costs in areas that generate it.
-
Employee “Involvement”
❒ P2 roles & responsibilities for all employees
❒ Training & awareness programs
❒ Reward program for P2 suggestions & accomplishments
